Procedure
Step 1 Configure VLANs and IP addresses on the PW-side interfaces according to
Configure a routing protocol on the backbone network to ensure that devices can communicate
with each other. OSPF is used in this example.
Configuration details are not mentioned here.
After the configuration is complete, PE1, PE2, and PE3 use OSPF to discover IP routes to
Loopback1 of one another, and they can ping one another. Run the display ip routing-table
command on PE1, PE2, and PE3. You can see that the PEs have learned the routes to one another.
Step 2 Configure an Eth-Trunk in static LACP mode on CE1, PE1, and PE2, and add member interfaces
to the Eth-Trunk. Configure Layer 2 forwarding on CE1.
# Configure CE1.
[CE1] vlan batch 10
[CE1] interface eth-trunk 20
[CE1-Eth-Trunk20] port link-type trunk
[CE1-Eth-Trunk20] port trunk allow-pass vlan 10
[CE1-Eth-Trunk20] mode lacp-static
[CE1-Eth-Trunk20] trunkport GigabitEthernet 1/0/1 to 1/0/4
[CE1-Eth-Trunk20] quit
# Configure PE1.
[PE1] interface eth-trunk 10
[PE1-Eth-Trunk10] mode lacp-static
[PE1-Eth-Trunk10] trunkport GigabitEthernet 1/0/1 to 1/0/2
[PE1-Eth-Trunk10] quit
# Configure PE2.
[PE2] interface eth-trunk 10
[PE2-Eth-Trunk10] mode lacp-static
[PE2-Eth-Trunk10] trunkport GigabitEthernet 1/0/1 to 1/0/2
[PE2-Eth-Trunk10] quit
Step 3 Create an E-Trunk and set the LACP priority, LACP system ID, E-Trunk priority, local and
remote IP addresses, time multiplier for detecting hello packets, and interval for sending hello
packets.
# Configure PE1.
[PE1] e-trunk 1
[PE1-e-trunk-1] quit
[PE1] lacp e-trunk priority 1
[PE1] lacp e-trunk system-id 00E0-FC00-0000
[PE1] e-trunk 1
[PE1-e-trunk-1] priority 10
[PE1-e-trunk-1] timer hold-on-failure multiplier 3
[PE1-e-trunk-1] timer hello 9
Issue 01 (2011-07-15)
MPLS LSR IDs of PEs
VSI name on PEs
Interfaces to which the VSI is bound
NOTE
l The AC-side interface and PW-side interface of a PE cannot be added to the same VLAN; otherwise,
a loop occurs.
l When configuring OSPF, configure PE1, PE2, and PE3 to advertise 32-bit loopback addresses.
